A. Do we want/ need to, or are missile effects for the defense of the nation/soveriegnty going to be more effectively brought into play by aircraft and naval vessels?

C. Or maaayyybe is it about situating the estimate because the Army wants PrSM? (Which it might be entirely justified in, it seems pretty damn awesome- but just come out and make the case for it)
